The most notable works linking HMXBs with star forming structures in the Milky Way are from [1]} and [2]} (B12 and CC13 hereafter). Both propose to study the clustering of HMXBs and OB associations, and mostly view the HMXBs and clusters as a population. The former adopt a statistical clustering method, and the latter propose age determinations and migration distances by finding spatial offsets between Galactic spiral arms and their HMXB sample.
